Phuljhadi and phuljhuri are the same word carried into Hindi and Bengali from a shared root meaning "flower shower," and both describe the identical thin stick that throws a steady spray of sparks when held at arm's length. Tamil buyers rarely use phuljhadi at all. Mathaappu is the word printed on Tamil-language crackers ads and used at the shop counter, confirmed by Tamil Wiktionary's own entry for the term. Telugu's kakarapuvvotti is a compound of "kakara" (a crackling sound) and "puvvu" (flower), describing the same spark-shower effect the Hindi name references from the other direction. See the sparklers range.

Chakri, chorki and chakra all trace to the same Sanskrit root, chakra, meaning wheel or disc: the word describes the spinning motion itself, not a regional variant of a different product. A flat, coiled firework that spins on the ground once lit is chakri on a Hindi-belt catalogue, chorki in Bengali usage, and built on the chakra root in Kannada, where the compound chakra pataki ("wheel firecracker") names the same spinning ground item. See the ground chakkar range.

Tamil, Telugu, Kannada and Bengali sellers all print "rocket" on their catalogues rather than translating it, because the format itself (English rocketry) entered the Indian trade under its English name. It is the one word every regional catalogue keeps as-is. Bengali retains two extra umbrella words worth knowing if you're reading a West Bengal price list: rong moshal (literally "colour torch") for handheld coloured-flame novelties, and tarabaji as a general term covering sparkler-and-spark-shower items as a group rather than one specific product. See the rockets range and the fancy novelties range.
