I made those Eldrich Invocations and I will apreciate some feedback.

Those are the Invocations.

Tricky Friend.

Prequisite:5th level

You always have the spell Summon Fey prepared. You can cast it once per long rest without a spell slot. When you cast it that way you can modify it to doesn't require Concentration. If you modify it this way it's duration becomes 1 minute.

Power from Fear.

Prequisite:5th level, ability or Warlock spells that gives the Frightened condition.

When you give the Frightened condition to a creature, you gain 2d10+your proficiency bonus Temporary hit points.

Do you have any ideas for more;;;

Tricky Friend is basically Fey Reinforcements from the Fey Wanderer Ranger subclass. But in Tasha's, it's unlocked at level 11, so level 5 feels a little low.

Power from Fear is cool. I can see some nice combination with Armor of Agathys. 2d10 is a lot though. At level 5, the max value would represent about half of your max HP... Maybe 2d8 or 2d6.
