No, only candles of 51%+ beeswax may be used.
From the USCCB:
"Since the National Conference of Catholic Bishops has never employed the above-noted faculty to permit the use of materials other than wax in the production of candles, the use of such other material either in substitutes for or in imitations of candles is not permitted in the liturgy. Therefore, oil lamps may be used only "in the case of the sanctuary lamp," as indicated above. Candles made of wax are to be used in the celebration of the Mass and other liturgical rites."
Roman Catholic AnswerCandles at a Wedding usually are just the normal candles used at Mass, as most Catholic weddings should take place with a Mass. Often the Paschal candle may be used, at the discretion of the pastor. The candles on the altar are required and both represent the light of Christ and respect for the Mass itself. "Unity candles" are not an approved option for a Catholic wedding.
Candles are used in the Catholic Church as a symbol of light and prayer. They represent Christ as the light of the world and are often lit during Mass, prayer services, and other sacraments to symbolize the presence of Christ. Candles are also used as a way to focus and enhance prayer intentions.
There are seven sacraments in the Catholic Church, to the best of my knowledge, the only one for which candles are NOT called for is Confession. Of course in an emergency, anointing and baptism could be preformed without candles, but I know of no situations in which a wedding would be such an emergency that they couldn't get candles.
tallow candles were considered household items, considered very affordable. Beeswax candles however were used mostly for the upper class and catholic church since beeswax is harder to obtain.
Catholic Christmas candles hold significance in symbolizing the light of Christ, representing hope and the presence of Jesus during the holiday season. They are often used in religious ceremonies and decorations to emphasize the spiritual aspect of Christmas.

Beeswax candles are most often used but regular dollar store candles are fine. These candles are blessed "en mass" or in bulk during the ritual of Candlemass. Colors of the candles play a big part of the rituals with various colors burned for different blessings.

Candles used in Judaism usually don't have names, other than the names of the occasions they're used on, such as: Shabbat candles, used on Shabbat Havdalah candles, used on Havdalah Hanukkah candles, used on Hanukkah Yahrzeit candles, used for someone's Yahrzeit

No, candles are not demonic symbols. Candles are used for many purposes, including religious rites. And this can include any practitioner or any belief. The only symbology of the candle is that placed on it by a user. And anyone looking at a candle can and may impose his own symbolism to the humble candle. It can have any or no meaning at all, and, if it has meaning, it is subjective. Candles are used commonly in a Christian Catholic church, or a demonic or satanistic ritual. Black candles are used in satanic rituals. Black representing darkness or Satan, while white candles represent purity or the light of Christ.
