Short answer: you probably can't...
Unless you own enough asic's to controll 1% or 2% of the total network's hashrate so you'll have a decent chance of solving at least one block/day, you'll have to join a pool instead of solo mining (at least in order to accelerate transactions... You can solo mine when you have less hashrate, but the odds of solving a block in a decent timeframe would drop, making your acceleration worthless). When you join a pool, it's the pool operator that can increase a transaction's priority not you.

sad to hear actually some of my transactions stuck in network tried many free accelerator but nothing working

Well, there are other options depending on your specific case:

• Did you opt-in RBF? In this case, your wallet will probably allow you to create an rbf tx (they call it "increase fee" or "bump fee")
• Was there change going back to your wallet? In this case you can do a CPFP
• You can pay a big pool to increase your tx's priority... ViaBTC is known to be a reliable partner for this
• You can double spend one of the unspent outputs used as an input for your tx, altough this method has only a small chance of succeeding
• If you wait about 2 weeks, most nodes will prune your unconfirmed tx from their mempool since this is the default maximum age of transactions... Some nodes do have different values tough, so after ~2 weeks your tx won't be completely gone, so it won't propagate completely. This way you can re-spend the same unspent outputs (the same as the previous option, but a bigger chance of success)
• You can rebroadcast your transaction every ~week so it stays in the mempool of the nodes, eventually the mempool size will decrease and your tx will get confirmed (actually the oposite of the above 2 options)
• There are some free accelerators aswell... Antpool allows you to increase your tx's priority a very little bit, but if you grossly underpayed this will not really help you all that much. ViaBTC accepts 100 tx's/hour for free, but you need a minimum fee of 10 sat/byte to qualify AND you have to be really fast to get one of the first 100 spots

Don't pay random people to "mine" your transactions. This is impossible. Only a big pool that solves at least a couple of blocks a day has any chance of making such a promise. Scammers prey on people that have stuck transactions tough.

My fee was 214.105 sat/B   and i paid 5.40$ fee for 100$ transaction i don't this its low fee .
i am using blockchain wallet so no RBF available yet

214 sat/vbyte seems reasonable at this moment in time: https://jochen-hoenicke.de/queue/#0,24h
There are ~3Mb of tx's that payed > 200 sats/byte
There are ~0.6Mb of tx's that payed >250 sats/byte

Your fee is somewhere in that range. IF the amount of new transactions per timeframe is lower than the amount of transactions getting into a block at the same timeframe, i can guesstimate your tx will get confirmed within "reasonable" timeframe.
However, the influx of transactions can be rather unpredictable, no way of telling for sure.

It seems like a 5% fee is on the high side, but remember: bitcoin does not care about fiat values... It cares about the size of the transaction, and the transaction size is determined by the type of wallet, the number of inputs and the number of outputs... It doesn't matter if each input has a fiat value of $1 or $1000.

Since your fee is relatively high, the transaction should confirm in the early hours (europe time).
But a small pump/dump of the BTC/USD price could definitely add more transactions to the mempool.

For the future, you might want to consider using a proper wallet. Not only will you have the ability to replace transactions / increasing the fee, but you'll have a more secure storage of your keys.
Web wallets should be avoided whenever possible.
