it is possible to connect several resistors with different resistances so that they all have the same potential difference? if so, will the current be the same through all resistors?

By "several", I'm going to assume "3", and take each possible case -
1 - All 3 in series - current through each will be the same, but voltage across each will be according to E=IR, and since R will be different, so will V
2 - Two in series, in parallel with the third - The third will have the voltage of the source across it, while the two in series will split that same amount of voltage, so no.
3 - All three in parallel - All three will have the same voltage across them, i.e, the voltage of the source. But since the R of each branch will be different, so will the I.

yes this connection is called parallel and one end of each resistor is connected to each side of the power source.
The current through each resistor will be E/R since each resistor a different value the current will be different.
The only limitation is that I^2*R is less than the power rating of each resistor.

In some cases yes. But if their resistances are different, the currents through them will have to be different if the potential across them is the same.
