As soon you find a block you will get you reward. Please wait a little bit more time.
Since you start to mine your hashrate grows gradually. Please wait. The pool determines your hashrate based on the amount of shares sent by your mining rigs (workers). This value could be a little bit different from reported hashrate (in your mining software).
No. At the moment it is: 1 EXP
PPLNS is a collective pool. Miners work together to find a block. When it is found they split the block reward based on their hashrate. At SOLO mining pool each miner works alone. However if he finds the block he gets the complete block reward himself.
Transaction data is recorded in blocks. New transactions are being processes by miners into new blocks which are added to the end of the blockchain.
At SOLO mining pool the miner who finds the block receives all the block reward.
It depends on your hashrate and network difficulty.
Mining is probabilistic in nature: if you find a block earlier than you statistically should on average you are lucky if it takes longer, you are unlucky. In a perfect World you would find a block on 100% luck value. Less then 100% means you were lucky. More then 100% means you were unlucky.
Share is a possible valid hash for the block. Shares are beings sent by your rigs to the pool to prove their work. Check this article.
