I need a few examples from As You Like It that show the relationship between Rosalind and Celia.

These two are more like sisters than cousins, given their
close camaraderie and their ability to confide in one another. Celia, sensing Rosalind's
sadness, says "I pray thee, Rosalind, Sweet my coz, be merry." There is a playfulness to
their relationship, with Celia beingt he instigator of the teasing, which is ironic,
given Rosalind's tendency to play games and speak riddles when she is disgusied as
Ganymede.

When Celia learns that Orlando is in the forest,
she teases Rosalind, noting that she blushes ("Change you color?") when she mentions the
necklace Orlando gave her. Celia, wanting to build her excitement at the discovery, says
"Oh wonderful, wonderful, and most wonderful, and yet again wonderful, and after that
out of all whooping!” ("Whooping" in this case most likely meaning "hoping") Once
Rosalind figures out who Celia is asking about, Rosalind asks a number of questions
about him and then says "Answer me in one word." Celia protests, saying "You must borrow
me Gargantua's mouth first; 'tis a word too great for any mouth of this age's
size."

Both women are separated from their lovers and help
each other in requiting their affections for these men. It is clear they want to help
the other towards happiness, and do so with real affection.
