Based on the glyphs you show, your mappings seem correct to me.

The vowels that you did not specify look like normal letters alif, ha', ya', and waw, so why shouldn't they be encoded with the normal code points?

The initial form of vowels seems like the same letters preceded by a hamza on a ya' carrier, which is probably the Kurdish way of spelling the glottal stop.

So I would propose these encodings: 
Latin 	Arabic 	Arabic Initial 
a 	ا (U+0627) 	ئا (U+0626 U+0627) 
e 	ه (U+0647) 	ئه (U+0626 U+0647) 
ê 	ێ (U+06CE) 	ئێ (U+0626 U+06CE) 
î 	ی (U+06CC) 	ئی (U+0626 U+06CC) 
o 	ۆ (U+06C6) 	ئۆ (U+0626 U+06C6) 
u 	و (U+0648) 	ئو (U+0626 U+0648) 
û 	وو (U+0648 U+0648) 	ئوو (U+0626 U+0648 U+0648) 
ç 	چ (U+0686) 
g 	گ (U+06AF) 
j 	ژ (U+0698) 
ll 	ڵ (U+06B5) 
p 	پ (U+067E) 
rr 	ڕ (U+0695) 
y 	ی (U+06CC) 
 
 
I hope everybody can read HTML e-mails. Just in case, I attach a text version.
