Finding the different numbers whose sum squares give a number which has same digits I could find the following numbers

$$1+2^2+3^2+4^2+5^2=55$$ $$1+4^2+7^2=66$$ $$2^2+3^2+5^2+7^2+11^2+13^2+17^2=666$$

Are there other numbers ?

It's not entirely clear what is wanted here. As I noted in the comments, Bateman proved that, given any $s\ge5$, every sufficiently large integer is a sum of $s$ distinct squares. Also, the Online Encyclopedia of Integer Sequences has the complete list of numbers that cannot be expressed as a sum of distinct squares; the largest is 128. But OP's examples have more structure; the first two, the numbers being squared are in arithmetic progression and start with 1; the third, the numbers being squared are the first few primes. Maybe OP will clarify just what conditions are wanted here.
