Answer 1

Assuming you want the array sorted :

import collections    
counter = collections.Counter(SampleArray)
res = []
for key in sorted(counter.keys()):
    if counter[key] == 1:
        res.append(key)
    else:
        res.extend([key+str(i) for i in range(1, counter[key]+1)])

>>> res
['champ', 'king1', 'king2', 'mak1', 'mak2', 'mak3']
