One question, I have 2 creatures that I have declared blockers, one is 7/7 that blocked first and the second one is 6/6, my opponent declared an attacker a 6/6 with first strike, it is legal to hurt only the 6/6, and not the 7/7 that declares that block first.
As the defending player, you don't choose which creature "blocks" first. Rather, in the case when multiple creatures block a single attacking creature, as in this case, the active player chooses the order in which those blocking creatures assign combat damage. This happens right after blockers are declared (C.R. 509.2). This answer doesn't change if one or more of the attacking and blocking creatures have first strike.
I think it's wrong to explain, let's put it that way; they attack me with a 6/6 with a first strike, I lock with a 7/7 and a 6/6, I block first with the 7/7 and then with the 6/6, my opponent can only hurt the 6/6 that blocks from last?

Again, you don't choose which creature "blocks" first in this scenario. When the combat damage step begins, only creatures with first strike (and double strike) can assign combat damage, since the attacker has first strike (C.R. 702.7b). Thus if your opponent chose earlier to assign combat damage to the 6/6 creature first, the attacker assigns all its combat damage (which is 6 because its power is 6 [C.R. 510.1a]) to that creature and assigns none of it to the 7/7 creature (C.R. 510.1c). And if your opponent chose earlier to assign combat damage to the 7/7 creature first, the attacker assigns all its combat damage to that creature and assigns none of it to the 6/6 creature (C.R. 510.1c). In the next combat damage step, only "the remaining attackers and blockers that had neither first strike nor double strike as the first combat damage step began, as well as the remaining attackers and blockers that currently have double strike" will get to assign combat damage (C.R. 702.7b).
Oh I understand much better, sorry if it cost me to understand the first thank you again!
one more question, if I block with 2 again and a creature that I control has first strike, and the attacker has first strike, how the damage is solved

If in addition to the scenario in comment 3, one of the blockers has first strike, that blocker can assign combat damage in addition to any other attacking and blocking creatures with first strike (or double strike) during the first combat damage step (C.R. 702.7b). In the next combat damage step, only "the remaining attackers and blockers that had neither first strike nor double strike as the first combat damage step began, as well as the remaining attackers and blockers that currently have double strike" will get to assign combat damage (C.R. 702.7b).
