If I send some bitcoins to some address, and I pay the proper fees, how sure am I that it will be included in the next block? Are there any guarantees if I want my payment to be included in the next block that is mined?
Actually just pay recommend fees you can get your transaction sent less than 10minutes. Guaranteed
is there no limit to the number of transactions in a block? what if everybody pays recommended fees? so some will still not make it? am i right?
there is a limit to that. more transaction means more size, and the block size are limited to 1mb
as of now does the 1 mb limit always get full?
according to this

nope, not even close.
does it mean if we send with so little fee it can still make it to the next block? in electrum you can put the fee that you like so is it ok to put .0000001 and be confident that it will make it on the next block?
