Hausa
the Hausa words for numbers up to six can be preserved.
0: sifili
1: daya
2: biyu
3: uku
4: hudu
5: biyar
10: shida
numbers after six can be formed the same as numbers after eleven, using the word "sha", which means "and".
11: shida sha
12: shida sha biyu
13: shida sha uku
14: shida sha huɗu
15: shida sha biyar
multiples of ten in Hausa are loanwords from Arabic. to make multiples of six, we can alter these words to all end with -shida, the Hausa word for six.
20: ashida
21: ashida da daya
22: ashida da biyu
23: ashida da uku
24: ashida da hudu
25: ashida da biyar
30: talashida (this apparently means cheek, so it might not work)
31: talashida daya
32: talashida da biyu
33: talashida uku
34: talashida da hudu
35: talashida da biyar
40: arbashida
41: arbashida daya
42: arbashida da biyu
43: arbashida uku
44: arbashida da hudu
45: arbashida da biyar
50: hamshida
51: hamshida daya
52: hamshida da biyu
53: hamshida uku
54: hamshida da huhu
55: hamshida da biyar
for large powers of ten, Hausa puts the word for the power before the word for the digit, so this is also how Hausa uses nif and the -exian series. Hausa phonology doesn't allow the sequence /ks/, so -exian becomes -eciyan.

101: nif da daya
102: nif da biyu
103: nif da uku
110: nif da shida
111: nif da shida sha

1000: nif shida
