/f/ is a marginal phoneme, appearing mostly in loanwords. Other than that, [f] also appears as the allophone of /v/ word-finally and before voiceless consonants.
/v/ has can be either a fricative [v] or an approximant [ʋ], but it's usually somewhere in between the two, a weak fricative. It has several allophones:
A lot of speakers pronounce /vu/ as [wu]. Some speakers always pronounce /v/ as [w] word-initially, except before front vowels.
/kv gv xv rv/ coalesce into [kʷ gʷ xʷ ɹʷ]
Many speakers pronounce /v/ as [ʋ] or [w] after /ɫ/, /j/ and /ʎ/
/v/ is devoiced to [f] word-finally and before voiceless consonants.
[ɣ] only appears as the allophone of /x/ before voiced stops and fricatives. A lot of speakers elide it completely (usually with compensatory lengthening) , pronouncing /pɔxdi/ as [pɔːdi] or [pɔdi] instead of [pɔɣdi].
A minority of speakers speakers may pronounce the intervocalic clusters /xr xɫ xʎ/ as [ɣr ɣɫ ɣʎ] or elide /x/ before these consonants, meaning that /axri/ may be pronounced as [aɣri], [aːri] or just [ari] instead of the usual [axri].
/n/ becomes [ŋ] before /k g x/. /ŋ/ as a separate phoneme is marginal and occours only word-initially. Many speakers elide this word-initial /ŋ/ altogether.
Several speakers pronounce word-initial /g/ as [ŋ]
/n/, /r/, /ɫ/ and /ʎ/ may be syllabic
/r/ is usually realized as a trilled [r], but may be sometimes a flapped [ɾ], especially when not syllabic
