This is the down side of using comparators. NOT MP friendly. When one player enters, the command block is already triggered.
Solution 1:
This will constantly re-apply the perk to anyone in range.
Setup:
/scoreboard objectives add inRange dummy
Clock(20tps Fill Clock)
/scoreboard players set @a inRange 0
/scoreboard players set @a[x=<X>,y=<Y>,z=<Z>,r=<Range>] inRange 1
Run commands that will give the perks using the player selector @a[score_inRange_min = 1]
Solution 2:
Simpler version of Solution 1
Clock(20tps Fill Clock)
Run commands that will give the perks using the player selector @a[x=<X>,y=<Y>,z=<Z>,r=<Range>
Solution 3:
Give perk upon entering range.
Setup:
/scoreboard objective add inRange dummy
Clock(20tps Fill Clock)
Run Commands that will give the perks using the player selector @a[x=<X>,y=<Y>,z=<Z>,r=<Range>,score_inRange = 0]
/scoreboard players set @a inRange 0
/scoreboard players set @a[x=<X>,y=<Y>,z=<Z>,r=<Range>] inRange 1
Explanation:

Solution 2:
Straight up run a command on all players within range
Solution 3:
Run a command on all players that are in range but have not been marked aka. just entered the range. Then reset the score and mark all players in range.

Just enter this command into a command block:
/summon Wolf ~ ~1 ~ {Owner:Notch}
Of course, the name Notch could be replaced with the player's name that you wanted to have it tamed to. @p does not work! (The command will generate a tamed wolf one block above the command block, tamed to the person of your liking.)
Best Answer
There is no command to change a player's name.
As a workaround, you could fake it by hiding the player's name whilst teleporting a named entity onto them.
To hide a player's name tag, put them on a separate team and change the

You can teleport that entity to the player on a clock with something like:
